In order to get the same results we will reset the mesh options.
- Open the preferences window selecting Utilities->Preferences.
- Select the Meshing branch, click on Default values and then Apply.
- Now select Mesh->Reset mesh data in order to ensure the geometry has no meshing property attached.
- Select Mesh->Generate mesh.
- A window comes up in which to enter the maximum element size for the mesh to be generated. As default value could change from one version of GiD to another, insert 2 to get the same results as shown in images OK.
- A meshing process window comes up. Then another window appears with information about the mesh generated. Click View mesh to visualize the mesh.
- The result is the mesh in Figure. There are various surfaces and volumes. By default, mesh generation in GiD obtains unstructured meshes of triangles on surfaces and tetrahedra on volumes.
